Network error on backup download

[Canapin (Coin-coin le Canapin)]

My co-admin told me he couldn’t download a backup from the received email because the download crashed at roughly 50%.

I tried and experienced the same. The archive download works well until it stops with “Failed - Network error”.
Trying to resume on Chrome returns “Failed - Unknown server error”. I had no issue the last time I downloaded backups from this server (months ago). (this is expected)

Any idea?

Network error on backup download

I tried downloading a backup from another forum and experienced the same. Can someone try to replicate on their own instance? On both sites the download fails after 30 seconds. Moving this to Bug because I’m quite sure this is not just me.

Hi,

I’m Canapin’s co-admin

Trying to resume on Chrome returns “Failed - Unknown server error”. I had no issue the last time I downloaded backups from this server (months ago).

I’m wondering whether this is due to the one-time link. You can’t download a backup twice with a single link. So, when it fails once, resuming the download is probably cancelled by Discourse itself.

@Canapin

the download crashed at roughly 50%.

i think you need to change the way you’re downloading the backup

Backup upload not working

Press ⌘ + Space → type Terminal → Enter Run your command scp -C root@domain.com:/var/discourse/shared/standalone/backups/default/cate-s-community-2025-10-17-161933-v20251016143343.tar.gz . -C → enables compression root@domain.com: → your server’s login /var/discourse/…tar.gz → remote path . → save it in your current local directory (e.g. /Users/yourname)

Well, there sure are other ways to download backups, but I’d rather identify the cause and fix this particular issue

probably this, but this is not the only issue preventing full download of the backup via web browser

As an update, the forum was migrated to another server (for unrelated reasons), but the issue persists. The backup download (3.3 GB) always fails.

I have been experiencing this same issue for over a week. Fully updated twice in that time but the issue still persists. Self-hosted on IONOS. Backup size 1.5GB.
